UNITE@ S'E GEORGE W. DETTNER, F SAN Application led February RULE IiI'TjB. AND CUT-OFF.

rl`his invention relates to a rule miter and cut-oli", and its object is to chine which is capable ot cutting as well as n'iitering them both at produce. a maotl rules the ends and between the ends of the rule.

' lt will be understood by those skilled in the art that printing rules must be mitered not only at the ends, but

tween the ends, and in addition,

oil smoothly,

be provided tor cutting the which latter, iii this machine, a saw which does not distort rrequently the case where the iiile is iii a shearing machine.

Other objects of the inven as the description proceeds.

Mounted upon the table 4e, is a. square 8.

This square is pivoted at 9,

forming the means for conead to the operating said handle being pivotally inoiinted on a pin 15 secured to the underside of the table Ll. verse recess to receive a roller is )ourn The slide 5 has a transsmall roller 17. rl`his alled u ion a steel in 18 and' it is recessed to receive three cutters 19, 20 and 21, said cutters having any desired tace angle, and being held by means ot the set screws 2Q,

in the roll in place Q3 and 211.

rFlic roler held iii a lined position to eifect the cutting by means ot a pin Q5, which passes through the. upper portion ot the head 5, and into any one oit 2i) in said roller 17.

'ihe pin Z5 passes t three holes 27, 28 or hi'ough a bushing 3U and has a spring 3l surrounding it to hold it normally in the position shown in F ig. 1. The bushing is threaded into the slide 5 to secure it and the pin spring in place.

At the side ot with its surrounding7 the slide 5, there is a rule,

or flat bar, 33, which is held in place by the counter-sunk screws 311 in turn holds a saw 3 and 35, and said plate 6 in place.

The saw is adjusted to take a deeper or shallower cut by setting up a screw 37 at the back of the slide 5, so that by turning the rule to be cut over it is possible to saw oit a rule double the thickness ot the space allowed at the points G and l/v'hen a rule is to e beveled on one end or the other it is unnecessary to remove the saw from the head 5,

is shown at 40 on the rule l1 (see to be made, the saw slide, and the square allow the ldesired space ards 2 and 3 for the whereupon, one of the used to cut the desired dotted lines Fig. 2).

It will be seen that some forward and so closely engaged but it a bevel such as Fig. 8) is is removed from the 8 is turned so as to between the standpassage of the rule, miters, such as 19, is recess 'in the rule (see while the head 5 has back movement,.that it is at its sides with the two standards 2 and 3, that it does not have any side movement, thereby insuring perfectly straightl cuts being produced,

while the depth ot the cut is regulated by the workman himself.

It is also to ment ot the table and chips shaved olii by Vt down between the tabl be noticed that the arrangeslide is such that any he cutters will drop e and slide, so as not m. LU

lll)

to interfere with the Said pose.

The operation of the inachine is as follows:

Presuniing the workman desires to bevel. the end of the rule, he will use the cutter of the forni shown at 20, and will determine the angle of the cut by shifting` the square 8 to the position he `deems necessary; the handle l will then be raised and lowered to shave ofi' the desired ine-tal frorn the end of the rule, if the rule is to be cut off, or is to beveled between its ends, the square 8 will be turned until one ef its edges is substantially parallel to the straight edge of table 4, this will allow a space of about one-quarter inch (l /L) between the standards 2 and 3, and the adjacent edge of the square 8; thereupon, the rule may be inserted and the head 5 is raised and lowered to either cut oda the end of the rule or to operate one of the cutters 19 or 2l to produce a desired bevel cut intermediate the ends of the rule. lf neeessary, during this operation, the saw may be removed.

That I claim is as follows, but inodiiications may be made in carrying out the invention shown in the drawings, and in the above particularly described form thereof., within the purview of the invention, as vdefined b v the annexed claims.

A machine of the class described coinprisinlg,r a base having a pair of vertical standards, grooves in said standards adapted to receive a sliding' head, a roller in said slide, a plurality of cutters in said roller, a pin in said slide adapted to engage a hole adjacent each of said cutters whereby each of said cutters may be set in working` position as required, a horizontal shelf on said standards, an adjustable initering square pivoted on said shelf and a lever for reciprocating said slide.
